Looks like if you use 4 slots you can't go beyond 2400MHz safely, and up to 3200MHz is dual slot. Again, no support for quadchannel, only dual. "A comment from Asus: " I’ve decided to provide some recommendations on DDR4 limitations concerning AM4 currently. As it stands the AMD code has restricted RAM tuning options which means many RAM kits at launch will not be compatible. This is the same for our competitors also. What we recommend is the following: If fully populating a system with 4 DIMMs (2DPC), use memory up to a max of 2400MHz. If using 1DPC (2 DIMMs) ensure they are installed in A2/B2 and use memory up to max of 3200MHz. The indication I have received from HQ is that AMD has focused all their efforts on CPU performance so far and will release updated code in 1~2 months when we expect improved DDR4 compatibility and performance." In short if filling all 4 DIMM's set your speed to 2400MHz and work up from there. If using 2 DIMM's put them in the A2/B2 slots and a max of 3200MHz should be possible. In our testing only the Crosshair board achieved 3000-3200MHz, the others were in the 2400-2666MHz range. BIOS updates will come!" It's all over internet, i won't link any site
Looks like it! The only officially known limitation is the lack of quad channel. I'm looking into getting 32/64Gb RAM for my main rig, i'm quite concerned on those points. 3D modeling, Game dev, Physic simulation and rendering, it all takes incredible amount of RAM.
So for start, only 2x 16GB. Well, saved cash... But I am more interested in performance jump between each memory speed.
DRAM speed has always been just a fancy number that doesn't mean anything in perceived experience. It's all marketing at this point imo.
Maybe to a certain degree but coming from 1600mhz DDR3 I'd love to be able to run 3200mhz DDR4. Some say it does next to nothing, some will tell you that faster ram makes quite some difference. I have a 1800x, Asus Crosshair Hero and 16gb of 3200mhz DDR4 and a Noctua cooler in my basket. Just shy of £1000. Now just waiting for reviews. Will also have to check if the Noctua is compatible. If the 1700/1700x look good in reviews, might just settle for one of those.
Noctua coolers, unless it's the special AM4 edition, are not compatible. Noctua have however stated IIRC that they will ship out free AM4 mounting kits for existing customers. So you might be stuck using the stock cooler until something is available, assuming it comes with a stock cooler.
Actually this info was posted pretty wide-spread for any cooling company in news bulletins: http://www.guru3d.com/news-story/noctua-offers-free-upgrade-kits-for-amd-ryzen-platform.html http://www.guru3d.com/news-story/no...al-edition-am4-cpu-coolers-for-amd-ryzen.html
While Quad channel RAM would be nice but I think that it is more important that AMD to do well. If AMD does well then maybe later down the road they can add Quad channel RAM maybe to another line of Motherboards.
The importance of RAM speed depends on CPU/IMC type too. Like Intel starting from Ivy benefits from faster than 1600 DDR3, 2133/2400 being the sweet spot more or less. Ofc the difference in performance in real world apps isn't groundbreaking and we don't know how Ryzen scales with memory speed, yet. So IMO a good-to-know thing atm for anyone planning a 4 DIMM build but nothing to worry about in the long run.
No need to worry guys , the support for different memory modules ( brand/capacity/speeds/latency) with higher speeds than 3200Mhz and up is already in the works in all Motherboard partners. Remember most of the motherboards are on their first Bios release and are working really hard on the Bios updates. Gigabyte is already pushing out new Bios like crazy ( this is a good thing ) , fixing and improving performance and compatibility - GIGABYTE GA-AB350-GAMING 3 (rev. 1.0) - http://www.gigabyte.us/Motherboard/G...-10#support-dl - F1 , 2017/01/23 , *First release* - F2 , 2017/01/24 , *Enhance STR compatibility* - F3 , 2017/02/14 , *Enhance DDR compatibility* - F4 , 2017/02/20 , *Enhance compatibility with DOS operation See here for more info - http://forums.guru3d.com/showthread.php?t=412876 . I will be getting beta Bios to test directly from my contacts in Asus and if they meet the expectations i will publish them Beta bios on that tread , also this is work in progress. As i am in contact with some friends that are the most respected AMD overclocking legends in the world , so do not worried i can reassure you we will get the most out of our Ryzen set ups. All in all DDR4-3200Mhz to start it's really really good for a brand new platform that has not even come out yet ,be patient.
It's cool. New platform always needs time to fix bugs and performance etc. As long as people stay aware and up-to-date everything should be fine.
Yes , you can edit timings. I'm awaiting for the new ROG MemTweakIt software to be posted at Asus website : https://www.asus.com/Motherboards/ROG-CROSSHAIR-VI-HERO/HelpDesk_Download/ , as you can see my good old friend Gino Asus it's working very hard pushing out new Bios , they have already updated their support page and the 4th Bios has been posted = Description / CROSSHAIR VI HERO BIOS 0702 Improve system stability File Size 5.51 MBytes update
